Packing sleeve for tightening bolt of plate link chain, has sealing lip that is prestressed against sealing surface during mounting of sleeve by elastic deformation of outer ring, until another sealing lip rests at another surface

摘要

The sleeve has a body (2), and two sealing areas, where the sleeve is made from polyamide. One of the sealing areas is designed as a sealing lip (10) at the body and surrounds the other sealing area designed as a sealing lip (8) by an outer ring (9) made from elastic material. The sealing lip (10) is prestressed against a sealing surface during mounting of the sleeve by the elastic deformation of the outer ring, until the other sealing lip (8) rests at another sealing surface.
